James Arnold Taylor took to the stage at Star Wars Celebration to host Dave Filoni and Simon Kinberg as they were joined by the cast of Star Wars Rebels including: Freddie Prinze Jr. (Kanan), Vanessa Marshall (Hera), Taylor Gray (Ezra), Tiya Sircar (Sabine), and Steve Blum (Zeb), to discuss what it was like to work on a Star Wars property and what we can expect from Season 2, which premieres at Celebration on Saturday evening.

After a few formalities, the panel kicked into the action with a surprise screening of a teaser for Star Wars Rebels' second Season 2. Contained within the trailer was bombshell after bombshell, which sent the crowd into a frenzy that almost rivaled that seen in Thursday's opening ceremony.

Here's what we saw:

- Darth Vader being ordered by the Emperor to hunt down the rebels on Lothal.- A balding, gray-bearded Captain Rex shows up, stating that any friend of Ahsoka is a friend of his. - Rex is working with a number of other, equally aging clone troopers.- Rex and his team take down an Imperial Walker- Hondo is returning!- A series of new bad guys were teased, ranging from a force sensitive being wielding a lightsaber similar to The Inquisitors.- Vader and Kanan embroiled in a lightsaber battle- Vader putting Ezra in a force choke.

Other notes:

When Filoni was asked if Ahsoka and Vader would face-off with each other, he simply said "It's all part of the story we need to tell you."

Finally, one other tidbit came from Tiya Sirca who may have potentially let slip a spoiler for season 2 by saying that "These guys are Sabine's family....presently." Following Season 1 of Rebels, rumors had surfaced suggesting that Sabine would eventually leave the Rebel team. Could it possibly be that these rumors are true?

It truly is an incredibly teaser and it proves that Rebels is going to continue to build on that brilliant finale to Season 1. With these familiar faces returning from The Clone Wars, it's safe to say that Season 2 is going to elevate Rebels to a whole new level.
